graphic bug - ocean horizon noise/static

Bilge_Rat · 11-17-22, 02:01 PM

I noticed this bug a few weeks ago, basically the area just below the horizon looks like the static you would see on old TVs. I posted screenshots, although it does not show up very well. It shows up most clearly in the tutorial. The rest of the ocean looks fine.

I switched to a NVIDIA 3070ti a few months back, but the bug was not present at the time. I thought it might be a driver issue so tried various drivers from the original 512.15 I was using when I bought my card to the newest 526.98, but no joy. I also tried changing the various in game graphic settings as well as those in the NVIDIA control panel, but again no fix.

Has anyone else noticed this and is there a workaround? I am also wondering if there was a recent change to the game code that might be causing this?

Huh, well, I think I see what you mean, I will check into it. I think it will be easier to demo with a video, maybe the devs know what this could be.

posted a video which shows the problem a bit clearer. Note it does not show up when using the binoculars or UZO.

Have you tried adding some anti-aliasing, such as 8x SSAA?
You may take a performance hit.

Also, running a lot of aniosotropic filtering such as 8X--especially without AA may do that.
Running less may give you more performance.

On nVidia cards, multi-frame anti-aliasing may help, too.

Yes, try some changes in your settings, lets see how that works.

I had a dream about this last night, sort of. In my dream I was watching someone's youtube video of Wolfpack and I could see some waves were stuck in a loop, very visibly repeating the same movement over and over ....

did some more testing, unclicking "Anistropic filtering" and reducing "water resolution" in game solves the issue, but other parts of the ocean look worse, so no free ride.

I am starting to think this is not a bug per se, but just the way the game renders water resolution at the highest setting.
